The main function of the civil air defense airtight casing is to protect the pipeline from external pressure and bombing when passing through the civil air defense area, and at the same time prevent internal gas leakage. In wartime, it can effectively block external dust, bacteria and toxic gases from entering the civil air defense project and ensure the safety of personnel. In normal times, it can be used as a sealing material for pipelines to pass through civil air defense walls to prevent leakage of water, gas and other media and ensure the normal use of the project.
In practical application, the selection and use of civil air defense airtight casing is also a science. First of all, it is necessary to select the appropriate type and specification of civil air defense airtight casing according to the specific needs and actual situation of the project. Secondly, in the installation process, the construction should be carried out in strict accordance with the relevant specifications to ensure the installation quality and sealing performance of the casing. Finally, it is necessary to strengthen maintenance and maintenance in daily use, and regularly inspect and replace it to ensure that it is always in good working condition.
As a special building material, civil air defense airtight casing plays an irreplaceable role in civil air defense basements, civil air defense projects and other places. In order to ensure the safety of personnel and the normal use of the project, we must pay enough attention to this kind of civil air defense equipment, strictly control its quality and performance, and strengthen its application and maintenance.
